2/3 x 3/4 =6/12=1/2
(Multiply numerators, multiply denominators, simplify)
2.5y + 3x = 27
5x - 2.5y = 5
Align the variables to make solving this easier.
2.5y + 3x = 27
-2.5y + 5x = 5
You can see that the 2.5y and -2.5y cancel each other out. Then add the 3x and 5x, and 27 + 5.
3x = 27
5x = 5
8x = 32
Divide both sides by 8.
x = 4
Now input that x into one of the equations to get y.
2.5y + 3(4) = 27
2.5y + 12 = 27
2.5y = 15
y = 6
The answer to this system of equations is x = 4, y = 6. (4, 6)
Hello :
<span>A. 5th degree polynomial </span>
Answer: 11/21
Step-by-step explanation: Subtract: 67 - 26 = 6 · 67 · 6 - 2 · 76 · 7 = 3642 - 1442 = 36 - 1442 = 2242 = 2 · 112 · 21 = 1121
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(7, 6) = 42. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 7 × 6 = 42. In the next intermediate step , cancel by a common factor of 2 gives 1121.
hope this helps
Y=-3/4x+2, thats the slope intercept form
